Distribuição espacial de espécies arbóreas de cerrado: filogenia e traços de defesa contra herbivoria
(Universidade Federal de São Carlos, 2010-03-02)
Herbivory is expected to promote an overdispersed distribution of traits in co-occurring plant species, since similar plants are more vulnerable to specialised herbivores. As long as conservatism of traits is usually ...
Estudo taxonômico das espécies de Heterospilus Haliday, 1836 (Hymenoptera, Braconidae: Doryctinae) em área de cerrado do Estado de São Paulo
(Universidade Federal de São Carlos, 2017-06-06)
Taxonomy and systematics are fundamental Sciences for categorization, description of species and how they relate and are distributed throughout the planet. Hymenoptera parasitoids are considered as the major components of ...
Estudo de interações de parasitoides de insetos endófagos em frutos do cerrado
(Universidade Federal de São Carlos, 2010-03-08)
Interactions between endofagous insects in fruits play an important role in ecological communities, since the seed survivorship and hence the successes in recruitment of plant populations are directed related to damage ...
Influência de borda sobre vegetação e microclima no cerrado paulista
(Universidade Federal de São Carlos, 2011-02-04)
There is much variation in patterns of edge influence (EI) within a region due to factors such as vegetation structure, adjacent land use, orientation and edge contrast, and assessment of this variation is important for ...

The degradation of natural grassland and open area remnants is still intense and affect environmental integrity of these ecosystems. The mixed-flocks of birds are a common feature in open environments which provide advantages ...
Características físicas do lenho em grupos fenológicos foliares de arbóreas de cerrado
(Universidade Federal de São Carlos, 2016-10-10)
Leaf phenological groups of cerrado tree species show significant differences not only concerning the maintenance of foliage throughout the year but also about reproductive phenology as the peak and duration of flowering. ...
The role of fruit crop size, diversity of avian frugivores and long-term temporal variation over seed dispersal effectiveness in a neotropical savanna
(Universidade Federal de São Carlos, 2020-03-20)
Fruit crop size may be a key-trait for attracting an abundant and diverse assemblage of dispersers, possibly leading to positive outcomes for seed dispersal effectiveness (SDE). Temporal changes in resources or frugivore ...
